One-of theobjects of y invention is to take care of the material which tends to escape from the material being conveyed, such as dust and 'chafi? from grain conveyed byra belt conveyor, and at thesame time to prevent the loss'ofthat material from the main body of material, as for example, preventing the loss-of dust and chafi' from grain, thereby avoiding the monetary-loss oflosingsuch Ina-- terial;

:The invention -is shown applied to grainconveying apparatus for :agrain elevator; but itwill be-underst'ood to have other uses Referring more particularly to the drawing, 1 is a bucket type belt elevator such as used in a grain elevator, 2 the enclosure for the same having a pit 3 and 1 chutes land 5 I closed with flapvalves 6.; nAb'elt conveyor 7- cooperates with 1 chute 5' and elevator 1. Above and below the opening 8 of chute 5 are ventilating hoods 9 in exhaust communication with pipes lOwhich unite in pipe 11 leading to dust filter-12. Fan 13 driven by a motor14 supplies the exhaust circulation in elevator enclosure 2. Exhaust pipe 17 leads to filter 12 from another conveyor (not shown). Dampers 18 and 19 areprovided in pipes-17 and 11 respectively, to shut ofithe exhaustin either pipe as'desired.

In operation, grain or other dust laden materialjis carried by conveyor 7 and discharged into pit 3 through chute 5 and hoisted by elevator 1 to a garner.

The dust released from the grain 7 is taken up through ventilating hoods 9 and drawn through exhaust pipes 10 and :11 to filter 12. c Accumulations of dust in the filter I 1 "v 12 willfall as solid matter to the convergthrough filter 12 from the converging bottom opening 16, and be deposited-on the buckets, of theelevatorbywhich it will: be lifted with the grain.
